6 Claims.

This invention relates to new and useful improvements and structural refinements in glaziers point setters, and the principal object of the invention is to provide a power operated setter of the character hereindescribed, such as may be conveniently and effectively employed for dispensing and driving glaziers points with the expenditure of a minimum amount of effort on the part of the operator.

This object is achieved by embodying in the structure of the setter a solenoid having a reciprocable armature which, in turn, is operatively engageable with the point setting mechanism, so that the setting or driving operation may be effected by simply depressing a switch so as to energize the solenoid.

An important feature of the invention involves the provision of resilient means for returning the point setting mechanism as well as the armature of the solenoid to their initial positions in readiness for the next point setting operation.

Some of the advantages of the invention reside in its simplicity of construction, convenience of operation, and in its adaptability to economical manufacture.

With the above more important objects and features in view and such other objects and features as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of the invention.

Figure 2 is a longitudinal cross sectional view thereof, showing the same in use.

Figure 3 is an end view looking to the right of Figure 1.

Figure 4 is a perspective view of a point engaging and setting member used in the invention.

Figure 5 is a perspective view of a solenoid supporting bracket used therein, and

Figure 6 is a fragmentary perspective view showing an end portion of a base plate used in the invention. t

Like characters of reference are employed to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, the invention consists of a glaziers point setter designated generally by the reference character Ill, the same embodying in its construction an elongated base plate 12, one end portion of which is provided with a longitudinally extending, channel-shaped guide l4 having an open outer end, as is best shown in Figure 6.

A solenoid designated generally by the reference character It is mounted on the base plate l2, this solenoid including in its construction .a cylindrical shell 18 containing a suitable wind- 2 ing 29 which, in turn, is supported by a stationary tubular core '22 as is best shown in Figure 2. The core 22 as well as the shell [8 are supported by a pair of end plates 24, 26, these end plates being preferably formed with integral, horizontally angulated brackets 28, 38 respectively, as will be clearly apparent. The bracket 30 of the end plate 26 is secured to the base plate l2 as at 32, while the bracket 28 of the end plate 24 is secured to the base plate by a pair of screw threaded, upstanding rods 34 provided with nuts 36. It is to be noted that the rods 34 pass through suitable apertures 38 with which the bracket 28 is formed and engage at their lower ends a pair of screw threaded apertures 39 provided in the base plate, as illustrated in Figure 6.

It is to be also noted that the bracket 28 is disposed in a position where it overlies the guide l4 in the base plate I2, and that it is formed with a longitudinally extending slot 40 and with a diamond-shaped opening 42, the purpose of which willbe hereinafter more fully described.

A vertical point magazine 44 having a diamond-shaped cross sectional configuration conforming to the configuration of the point with which the invention is to be used, has the lower end portion thereof secured by welding, or the like, in the opening 42 of the bracket 28, a transversely extending reinforcing strap 46 being welded 01' otherwise secured to an intermediate portion of the magazine 44 and also being secured by suitable lock nuts 48 to the upper end portions of the aforementioned rods 34, as is best shown in Figures 1 and 3. By virtue of this arrangement the magazine 44 is securely retained in a substan-. tially upright position, and it is to be understood that the lower end of the magazine is in communication with the guide M in the base plate l2, so that the points Ell may be individually and successively discharged from the magazine into the guide It, as will be apparent from reference to Figure 2. The points 50 are adapted to be stacked in the magazine 44, and a follower 52, assuming the form of a simple strap slidable in the magazine, is employed for urging the points 50 down-' wardly into the guide It, this being effected by providing the follower 52 with a laterally projecting ear 5% and anchoring a tension spring 56 at one end to this ear, while the remaining end of this spring is anchored to the aforementioned reinforcing strap 46 as at 58.

A point engaging and driving member 50, best shown in the accompanying Figure 4, includes a substantially horizontal portion 52 which is slidable in the guide it of the base plate i 2 and also includes an upstanding intermediate portion 64 terminating in an angulated upper ex-v remity B6.

The horizontal lower portion 62 of the member 50 is recessed as at 68 and is provided with a substantially V-shaped notch in, this notch being adapted to engage and receive therein approximately one-half of a point 56 after it is discharged from the magazine into the guide I4.

The recess 68* assures that the thickness of the bottom 12 of the recess is substantially equal in thickness to the point 50, so that only one of the:

points is engaged by the notch atone time, that is, so that only the lowermost of thepoints is engaged by the notch 10 when the member is slid in the direction of the arrow 14 see Figure 1) in order to drive the pointintothe-work.

Similarly, the guide M in the base plate.l2 isnoid, It, the stationary tubular core 22 thereof projects. at one end from the shell end plate 26 and contains a reciprocable armature 16, the oiiterendportion of which is formed with a, bore TBiaccUnimOdating a tension spring, 80. This spring is anchored at its inner end as at 82 to the armature 76, while the outer end of the spring is aiichored to a. transversepin 84 provided in the c6re22; the pin -84 also functioning as a stop for the armature 'lfiwhich is normally urged by the spring in the direction of the arrow 85 in Figure 2.

The inner end of the armature i5 is formed with adiametrically extending keeper notch 88 configurated as is best shown in Figure 2, this keeper notch being releasably engageable with a. substantially U-shaped tongue 90 which is wrappedaround and secured to the angulated upper end portion 68 of the aforementioned member fifl'b'y means of a suitable rivet, or the like, 92.

The outwardly projecting end portion of the core22lis. providedwith a longitudinal slot 94 in which is slidablea laterally projecting pin 96 provided, on the armature 16, whereby the armatur'e-- free to slide longitudinall in the core 22 but isprevented from rotating therein, as will be clearly apparent. In this manner, assurance isnhadthatthe tongue 59 is always aligned with the ho'thBB, so that the tongue is readily receivableinthe notchwhen the armature 16 is driven as indicated at 98 in Figure 2, upon energization of the solenoid :6-

Itj.may be explained at this point that the tongue Sllis preferably formed from non-magnetizable material,,so that the aforementioned member 60 is not afiected by residual magnetism in the armature "l6.

Tliesolenoid l6" receives its supply of electric current through a conductor It!) and a suitable switch I92, and as will be readily apparent, upon energiz'ation of the solenoid, the armature 16' thereof will be driven in the direction of the arrow 98 so that the tongue 90 is engaged by the notch 88"of the armature, after which the armatur'eltogether with the member 60 will be driven in the direction of the arrow 98 so that the notch 10 of the member 80 is brought in engagement with the lowermost of the points 50 and the lowermost point is driven into the frame I04 of the work; This is best shown in Figure 2, wherein the reference character I06 indicates a glass panel which is to be installed in the frame I64 and which is being secured in position by the points 50.

Finally, it may be explained that an intermediateportion 64 of the member 60 extends slidably through the slot 40 of the bracket 28, and

suitable spring I08 has one end portion H0 thereof secured or anchored to one of the aforementioned rods 34, while its remaining end portion H2 bears against themember 60, whereby the member-60 is returned to its initial position as soon as the solenoid I6 is deenergized and in readiness for the next cycle of operation.

It is believed that the advantages and use of the invention will be clearly apparent from the foregoing disclosure and accordingly, further description thereof at this point is deemed unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor ch'angesin the details of construction and arrahgen'ient'of parts may be resorted to without departing from'the spirit and scope of the inventionas claimed.
